Petunia plant named ‘Duesweledro’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Duesweledro’, characterized by its outwardly spreading to trailing growth habit; freely branching habit; early and freely flowering habit; large light yellow-colored flowers; and good garden performance.

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘Duesweledro’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia, botanically known as Petunia×hybrida and hereinafter referred to by the name ‘Duesweledro’.

The new Petunia is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new Petunia cultivars with early and freely flowering habit, and unique and attractive flower color.

The new Petunia originated from a cross-pollination made by the Inventor in August, 2005 in Rheinberg, Germany of a proprietary selection of Petunia×hybrida identified as code number F-12-09, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code number F-06-25, not patented, as the male, or pollen, parent. The new Petunia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Rheinberg, Germany in January, 2006.

Asexual reproduction of the new Petunia by terminal cuttings in a controlled environment in Rheinberg, Germany since March, 2006, has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Duesweledro has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duesweledro’. These characteristics in combination distinguish ‘Duesweledro’ as a new and distinct cultivar of Petunia:

-   -   1. Outwardly spreading to trailing growth habit.     -   2. Freely branching habit.     -   3. Early and freely flowering habit.     -   4. Large light yellow-colored flowers.     -   5. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. Plants of the new Petunia differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Petunia are not as vigorous as plants of         the female parent selection.     -   2. Plants of the new Petunia have smaller flowers than plants of         the female parent selection.         -   3. Plants of the new Petunia and the female parent selection             differ in flower color as plants of the female parent             selection have creamy white-colored flowers.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ primarily from plants of the male parent selection in plant habit as plants of the new Petunia are not as upright as plants of the male parent selection.

Plants of the new Petunia can be compared to plants of the Petunia cultivar Duesweexyel, disclosed in a U.S. Plant Patent application filed concurrently. Plants of the new Petunia differ primarily from plants of the cultivar Duesweledro in flower color.

Plants of the new Petunia can also be compared to plants of the Petunia cultivar Dancas 110, disclosed in U.S. Plant Pat. No. 17,288. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Petunia differed from plants of the cultivar Dancas 110 in the following characteristics:

-   -   1. Plants of the new Petunia were more compact than plants of         the cultivar Dancas 110.     -   2. Plants of the new Petunia had shorter internodes than plants         of the cultivar Dancas 110.     -   3. Plants of the new Petunia had smaller leaves and shorter         petioles than plants of the cultivar Dancas 110.     -   4. Plants of the new Petunia had lighter yellow-colored flowers         than plants of the cultivar Dancas 110.     -   5. Plants of the new Petunia had longer peduncles than plants of         the cultivar Dancas 110.     -   6. Plants of the new Petunia were more tolerant to cold         temperatures than plants of the cultivar Dancas 110.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrate the overall appearance of the new Petunia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

DETAILED BOTANICAL DESCRIPTION

The photograph and following observations, measurements and values describe plants grown in Rheinberg, Germany, under commercial practice during the spring in a glass-covered greenhouse with day and night temperatures averaging 18° C. and light levels averaging 4,500 lux. Rooted young plants had been growing for about 16 weeks when the photograph and description were taken. Plants were pinched one time about three weeks after planting.
